`This invention relates broadly tofstorm win-u` dows and more specifically' to improvements in the structure and form ofthe sash and support- Qne of the objects of the invention is to provide a storm sash for acasement Window of the outwardly swinging type whichis `o'lesigriedi'o accommodate adjustmentsfor the purpose ofven` tilation, Without disturbing the seated relation betweenthe sash with the windowcasing.

.Another objectlof the inventionis to `provide fa storm sash which maybe readily installed in either an old or modernbuilding and 'readily mounted or removed, afterthe initial installation without the use of tools.

x economic of manufacture and susceptible of assembly without modication thereof in window casings which areslightly out4 of square.`

Other objects and advantages more or less an#- cillary to the foregoing and the manner in which i all the various objects are realized willappear in the following description, Whichconsidered in connection with the accompanying drawing, sets forth the preferredembodiment of the invention.

Fig. 5 is a transverse sectional `view through a portion of a window similar to `that shown in Fig. 2, illustrating anualternate form of construction.

By way of illustration the `improved storm window is shown hereinas associated with a steel frame window of the easement type with the I storm sash adjacent the inner face thereof. It

`will be understood, however, that the use of the storm window." sectionli v"is tion in .which theilange I veted i0 theres?- S seated inthe were in thehead molding 1.4"

kerfs in the transom and 'base rail 22 are of suilicient width, that is double the glass thickness, to permit the pane23, adjacent the center i 26 cemented or otherwise affixed to either memberandthe sliding pane 23 may if desired be provided with a thumbgrip 21.

In operation the `initial assemblyof the `storm window is effected by nailing or otherwise securing the molding strips I4, `I5 and` I'B to the window casing or interior trim. 'I'he flanges on the' top and outer edges of the sash I0 may then be tted within the grooves inthe moldings I4 and I5, .the bottom strip or molding section I8 y 'www e l n groove;

being assembled by sliding the strip sidewise with the ange in the base of the sash engaged in thel groove therein. The flanges I3 on the sash Il are next inserted to their full depth into the grooves in the moldings I4 and I6 and while so held with the bottom of the sash in spaced relation with the stool I9 the strip or key 20 is inserted between the lower face of the sash and window -stgaol`L` the- .Weight of-L the .sashl and the interlockled relaton'of fthe flangesand grooves being sumcent to assure the stability of the assembly.

When metal trim is employed the plate or Jambl v" 50 (Fig. 5) may be formed with a groove 51 ftheh in for the reception of the flange |391'- the edge of.
